Abstract
This article describes some recently obtained results on the low-energy properties of the "Kondo quartet" model of two spin-1/2 impurities interacting with two channels (flavours) of conduction electrons. We shall particularly emphasize the connections between conformal field-theory methods and bosonisation approaches, which are first illustrated on the example of the single-impurity, two-channel Kondo problem. This article is dedicated to the memory of Claude Itzykson, and will appear in the Proceedings of the Conference "Advanced Quantum Field Theory", held in La Londe Les Maures, Sept. 1996 (Nucl. Phys. B, Proc. Supp.; V.Rittenberg, J.Frölich and A.Schwimmer eds.).
